GANG-PLOW FRAME.

SPECIFICATION formingpart of Letters Patent No. 289,376, dated December4, 1883. Application filed May 11, 1883. (No model.)

To ctZZ whom it may concern.-

Be it known that I, ETHAN S. BENHAM, a citizen of the United States,residing in Attica, in the county of Wyoming and State of New York, haveinvented certain new and useful lmprovementsin Gang-Plow Frames, ofwhich the following is a specification.

My invention relates to certain improvements in the frames ofgang-plows, all of which will'be fully and clearly hereinafter shown byreference to the accompanying drawings, in which- Figure 1 asideelevation. Fig. 2 is a plan or top view and Fig. 3 represents a back endview.

The frame consists of a series of longitudinal parallel beams or bars, aa a and a series of cross-bars, a a* a These bars are securely heldtogether by eyebolts 0, so that the frame is capable of a movement backand forth sidewise. On the top of the frame is a diagonal brace, c,rigidly fastenedto the cross-bars a rd by bolts 0, or in any otherequivalent way, for thepurpose of holding the bars a a par allel andkeeping the frame in position. The plows c are rigidly secured to theunder part of the beams by bolts or other similar means, a, and anykind'of plow adaptedfor plowing may be used. The front part of the frameis provided with a draw-bar, a, connected to it by the usual clevises,f. On the bar 0 is a series of holes, f, through either of which theclevis f may be secured for the purpose of adjusting or changing thedraft when required. Under the front ends of each of the bars a, a

i or well-known way. In gang-plows it is usual to have them attached toa rigid frame, so that they cannot be tipped to either side, like asingle plow.

By my invention a gang of plows may be as a readily handled as a singleplow, and may be tipped to either one side or the other without changingthe depth of the plows in the ground, thereby lessening the draft, andcausing the plows to be as easily held and guided as a single plow. Whenone plow moves to one side, all of the plows in the gang partake of thesame movement, (see Fig. 3, in which the plows are shown. turnedslightly to the right,) but they may be turned either way more or less,thereby adapting them to be used on side-hills or on uneven ground.

In place of the diagonal bar a a rigid frame secured to the bars a a maybe used and any well-known means may be used, in place of the eyeboltsfor securing a movable joint.

I claim as my invention- A gang-plow frame consisting of thelongitudinal bars a a a", jointed to the cross-bars a a asubstantiallyas specified, in combina nation with the diagonal bar 0",handles f andplows 0 all arranged for joint operation, substantially asand for the purposes described.
